This is a vey broad and generalized question, but im just curious if you guys think you can get 150 hp out of the GT's 5sfe (not at the wheel, btw), and if so, is it possible with 2 grand? I am still undecided if I'd rather make my suspention setup the focus of my car, or if I should make it swifter... id like to get 20 more hp out of the engine if its possible, as a realistic goal. Anyways, what are some basics that add decent power to the 5sfe? Someone mentioned to me about shaving my block down to raise compresion, but how reliable will my car be, and is that going to even add anything worthwhile without adding more problems? How about port and polishing the cylinder walls? I have no ideas really so ill let you all fire away instead...

You don't have to mess with the block. Shaving the deck will increase compression slightly, but will also slightly reduce displacement. It'll be better to shave the head. I personally have faith in the stock internals of toyota blocks... so I wouldn't even bother modifying things there unless I wanna go really big power. As for the cylinder walls... umm... I don't know exactly how you'd be able to 'port' them. I believe you have that confused with port & polish head. Anyways... getting an additional 20hp out of the 5SFE isn't that hard with 2 grand. To make a rough list: webcam regrinds (~ $400-500) Port, Polished, and milled head (~ $500-600 depending on shop... might be even less) Basic Bolt-ons, intake, header, exhaust, Under Drive Pulley, etc... (~ $500-600) With that... even crappily tuned... will put you well over 150 horses at the crank. My opinion on building the 5SFE... well... it has a very tall stroke (92 mm if I remember correctly) which hurts its n/a buildability the most... but by the time you reach that point (meaning revving to hit the max power)... you'll be pushing a lot more than 150 hp. Currently... it's not easy at all to make a high-powered n/a 4 cylinder with a lot of low-end torque (meaning under 4000 rpms). A platform such as the 7AFE would be a lot better to build n/a because of the block design. The 5SFE would be the better for forced induction because of its displacement... That's my opinion...
